Heavy Metals Mobilization And Bioavailability In A Tropical Estuarine Lagoon In South-West Nigeria

ABSTRACT Environmental issues related to heavy metals and their biological effects continously heightens investigation into the risk associated with their presence and accumulation in aquatic ecosystems globally. This study investigated the mobilization, partitioning, bioavailability and risk associated with the heavy metal levels in the Lagos Lagoon between September 2013 and February 2015. It entailed the division of the lagoon into five zones and sampling carried out on a seasonal bas...

Spatial Distribution Of Suspended Particulate Matter (Spm) In Mtwapa Creek And Funzi Bay - Kenya

AbstractSurface water concentrations of inorganic nutrients and suspended particulate matter (SPM) components were examined and compared between Mtwapa and Shirazi creeks in Kenya. This was aimed at assesing the ecological situation of the two creeks and determine the influence of sewage discharge. The results obtained were further compared with those from Ramisi, an estuarine system. Mtwapa recorded higher nutrient, chlorophyll a and phytoplankton carbon concentrations than Shirazi. The two ...

The Artisanal Fishing Gears, Crafts Technology And Their Efficiency In The Lekki Lagoon, Nigeria

ABSTRACT The water quality characteristics, artisanal fishing gear and crafts technology and the Fish fauna composition in the Lekki lagoon between March, 2006 and February 2008 were investigated. The water quality analysis indicated that salinity Is drastically increased recently in the lagoon (0.007 4.70%). This study identified three possible sources for saline water intrusion, beyond the sun put in the adjacent lagoons (Lagos and Mahin) salt water intrusion by subsurface flow thr...

Phytoplankton Biomass And Diversity At The Iyagbe Lagoon Lagos, Nigeria

ABSTRACTFluctuations in phytoplankton biomass and diversity in relation to environmental factors at the Tyagbe lagoon, Lagos were investigated monthly from October, 2004 to September, 2006. The water quality indices reflected seasonal changes closely related to rainfall distributive patter and tidal seawater incursion. Whereas air temperature, surface water temperature, total dissolved solids, transparency, sulphate, silica, dissolved oxygen, conductivity, salinity, chloride, pH, acidit...

Ecological Study Of The Molluscan Fauna On Intertidal Artificial Rocky Shore Of Tarkwa Bay Area, Lagos, Nigeria

Abstract The molluscan community living in the three moles of Tarkwa Bay, Lagos was studied monthly between April 2008 and March 2010. These moles are made of rock known as the west, training and east. They provide attachment surfaces for the settlement of littoral communities. The study investigated the physico-chemical parameters, nutrients, heavy metals concentration levels in sea surface water, algae and resident molluscs of the three moles. Molluscan diversity, feeding, guts conten...

Biomarker Responses Of Estuarine Macroinvertebrates Of Lagos Lagoon Exposed To Drill Cuttings

Abstract The toxicity, accumulation of hydrocarbon and selected heavy metals, and biomarker responses were investigated in three macroinvertebrate species of Lagos lagoon exposed to drill cuttings.

An Ecological Study On The Macrobenthic Invertebrate Community Of Epe Lagoon, Lagos

ABSTRACTAn ecological study of the macrobenthic invertebrates community of Epe Lagoon was carried out.

Evaluation of transport infrastrtural development In nigeria and its effect on the national economy [1981‐ 2004]

ABSTRACT Transport infrastructure is the fixed part of a transport system. Transport infrastructure development remains one of the major tools for achieving the much needed rapid economic growth in Nigeria. Hence, the study aims at investigating the effect of funding on transport infrastructure development and the implication of this to the economy. The scope of the study was confined within the time frame of 1981-2004. The researcher used GDP, Budgetary Allocation to Transport and the Contri...

The Prospects And Challenges of Maintenance in Onne-Port Operations

 ABSTACT This research assesses the challenges and prospects of maintenance in Onne ports operations. Data were obtained from eighty maintenance staff in Federal Ocean Terminal (FOT) and Federal Lighter Terminal (FLT) using questionnaire. Simple random sampling technique was used in selecting the sample used for this research. The Yaro Yamen formula was employed to determine the sample size. Data were converted from ordinal scale to interval scale and three hypotheses were tested w...

Assessment Of Port Performance: The Queuing Theory Approach (A Case Of Apapa Port Complex)

ABSTRACT This research focused on assessing the port performance: the queuing theory approach using Apapa port complex (APC) as the case study. The research was designed and carried out to answer among others the following questions: to assess the level of vessel turnaround time, traffic intensity, the waiting time of calling vessels at the port? Also, to determine the probability of vessel queuing on arrival at the port? To answer these questions only primary means of data collect...

Analysis Of Cargo Pilferage In Nigerian Seaports: Pre And Post Concession Eras

CHAPTER ONE INTRODUCTION 1.0 Background Information The seaports are very important to the Nigerian trade as practically all imports and exports move through the ports. The importance of the seaports is attested to by the fact that approximately 99% by volume of Nigeria total imports and exports are seaborne; Nigeria ports control 60% of import into West and Central Africa. The ports have served as a major determinant of how economic activities are distributed. The volume of...

An Evaluative Study Of Inland Water Transport Development In Nigeria.

ABSTRACT This is an evaluative study of Inland Waterway Transport Development in Nigeria. Three sets of 5 point Likert Scale questionnaire were crafted for the study for the following categories of respondents; National Inland Water Authority (NIWA) Staff, Ferry Operators and the Inhabitants respectively. Five research questions and five hypotheses were also formed for the study. Data collected were analyzed with descriptive and inferential statistics such as mean procedure and On...

An Econometric Study Of Tanker Shipping Services In Nigeria

ABSTRACT This research work titled „‟An Econometric Study of tanker Shipping services in Nigeria‟‟ aimed at examining the demand for tanker shipping services with the resultant crude oil to be exported from Nigeria to other parts of the world using a time series regression approach and correlations. The objective is to ascertain whether the demand for tanker vessels (tonnage) corresponds with the resultant volume of the crude oil available at oil terminal to be exported. O...

An Appraisal of Concession of Onne Port to Intels Nigeria Services

ABSTRACT This work is to appraise the concessioning of Onne Port to Intel Nigeria Limited, the extent to which port reforms has positively influenced the development of Port Operations at Onne Port. To evaluate the developmental changes that have occurred, the researcher used statistical tools like spearman rank order and chi-square to analyze the data collected from the population of port users. Some hypotheses were developed. The study reveals ...

PORT Concessioning and the Future of Nigeria Ports

ABSTRACT The inadequacies of Nigerian ports toward the delivery of quality services such as good infrastructure, cargo handling, vessel quick turn round time, corrupt and fraudulent tendencies has given rise to privatization and concession since this practices can brief about the required level of efficiency and effectiveness when compared with international standards. This research work would enable us ascertain the effects of concessioning of N...
